1. A hybrid automatic repeat request feedback method, characterized in that:
an HARQ-ACK codebook comprises HARQ-ACK information of M PDSCHs, wherein the M PDSCHs are all scheduled by first-type PDCCHs, and the first-type PDCCHs are used for activating SPS configurations;
at least two of the M PDSCHs belong to the same SPS configuration, and/or at least two of the M PDSCHs belong to different SPS configurations;
an order of the HARQ-ACK information of the M PDSCHs in the HARQ-ACK codebook is arranged according to at least one parameter value, the parameter value comprises at least one of the following: cell indexes, BWP indexes, SPS configuration indexes, and PDSCH transmission moments of the M PDSCHs;
the order is firstly arranged according to the cell indexes respectively corresponding to the PDSCHs;
the order is further arranged according to the BWP indexes respectively corresponding to the PDSCHs under the condition that the cell index values are the same; and either
(a) the order is further arranged according to the SPS configuration indexes respectively corresponding to the PDSCHs under the condition that the BWP indexes are the same, and the order is further arranged according to the respective transmission moments of the PDSCHs under the condition that the SPS configuration indexes are the same; or
(b) the order of the HARQ-ACK information of the M PDSCHs in the HARQ-ACK codebook is firstly arranged according to the cell indexes respectively corresponding to the PDSCHs; the order is further arranged according to the BWP indexes respectively corresponding to the PDSCHs under the condition that the cell index values are the same; and the order is further arranged according to the respective transmission moments of the PDSCHs under the condition that the BWP indexes are the same.
